#### Description [src]

Emitted when the connection is closed.

The cause of this event can be

- If `g_dbus_connection_close()` is called. In this case `remote_peer_vanished` is set to `FALSE` and `error` is `NULL`.

- If the remote peer closes the connection. In this case `remote_peer_vanished` is set to `TRUE` and `error` is set.

- If the remote peer sends invalid or malformed data. In this case `remote_peer_vanished` is set to `FALSE` and `error` is set.

Upon receiving this signal, you should give up your reference to `connection`. You are guaranteed that this signal is emitted only once.

Default handler: The default handler is called after the handlers added via `g_signal_connect()`.
